T 0 all whom it may concern:

Be it known that I, GIPRIANO ANDRADE, J12, a citizen of the United States, residing at New York, in thecounty of New York and State of New York, have invented anew and useful Control Member forDifierentials, of which the following is a divisionalspecification.

My invention for differentials. My presentdevice is a part of my original application Serial No. 625,838, filed "March 15th, 1923, and'transferred from said original application to the present divisional application by direction of the Patent Office. The object of my present invention is, to provide a new form of control member for use in conjunction with hollow roller locking members.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which s Figure 1. is a form of control between the opposite roller locking members.

Fig. 2. is a diagrammatic view of the rollers and controls when performing a differential function. It will be understood that all of the rollers on each driven member are in contact with each other, as fully shown in Fig. 2. of my original application.

Similar letters refer to similar parts throughout the several views.

A is the driving member, B and B are the respective driven members. C are the locking rollers on driven member B and C are the locking rollers on driven member B. Each of the hollow rollers C and C has a recess G which recesses C contain an independent lug C which permits a limited circumferential motion of one roller in re lation to the other about the periphery of the driven member.

The functioning of said rollers and controls has been fully described in said original application.

As will be seen from the arrows in Fig. 2, the driving member A is rotating at the same speed as driven member B, and rollers C are locked between them. Driven member B is rotating faster than driving member A or driven member B, and therefore the rollers C, which are on driven member B are out of locking contact with driving member A.

It will be understood, that the independent element (3* need not be of umform relates to control members diameter for its entire length, but if it is made large enouglrto fittightly into one of the rollers, and yet has'a diameter smallerthan the diameterof the recess in the other roller, it will perform the function L of holding the two' rollers to limited circumferential motion, like the lugs'C in my original application. I

Iclaim: 1. Ina differential; a first locking roller having alongitudinal open space; a second locking, roller having longitudinal open space; and a third independent element adapted to "enter both of said'open spaces longitudinally, said independent element having a diameter less than the diameter of one of said longitudinal open spaces.

2. 'In a difler'ential; a first locking roller having a longitudinal open space; a second locking roller having a longitudinal open, space; and a third independent element adapted to enter both of said open spaces longitudinally, said independent element having a diameter less than the diameter of each of said longitudinal open spaces.

3. In a diiferential; a driving. member;

a first driven member; a second driven member; a first set of locking rollers between the driving member and the first driven member, said rollers being arranged in contact with each other, and having longitudinal open spaces; a second set of locking rollers between the driving member and the second driven member, said rollers being arranged in contact with each other, and having longitudinal open spaces; and independent elements adapted to enter the open spaces, of each pair of longitudinally positioned rollers, said independent element having a diameter less than the diameter of said longitudinal open spaces.

4. In a difierential; a driving member; a first driven member; a second driven member; a first locking roller between the driving member and the first driven mem= ber, said roller having a longitudinal open space; a second locking roller between the driving member and the second driven member, said roller having a longitudinal open space; and an" independent element adapted to enter the open spaces of each roller, said independent element having a diameter less than the diameter ofone of said longitudinal open spaces.

5. In a differential; a driving member; a

first driven memberya second driven anember; a first locking roller between the driving member and the first driven member, said roller having a longitudinal open space; a second locking roller between the driving member and theseconddriven-memher, said roller having a longitudinal open space; and an independent element adapted to enter the open spaces of each roller, said independent element having a diameter less than the diameter of each of :said

longitudinal open spaces.

6. In adifferential; a driving member; a firstdriven member; a-second driven member; a first set ,iof locking rollers between the driving member and the firstv driven member, said rollers beingarrangedrin contact With each other, and .having longitudinal open spaces; a second set .of-Zlooking rollers between :the driving .member and the second driven .member, said rollers being arranged vin contact with 'ieach other, and

having longitudinal open :spaces; and iinde- I pendent eleinents adapted to enterthe 'open spaces of each pair of longitudinally posit-ioned rollers, each .of said independent elements having a diameter less than the diameter of the longitudinal open space in one o'fsaid longitudinally positioned rollers.

7. lnxa differential; a driving member; a first driven member; a second driven mem- :ber; a first set of locking rollers between the driving member and the first driven member, said rollers being arranged in contact with each other, .and havinglongitudinal :open spaces; a second 'set of locking -rollers'between the :driving member andthe second driven member, said rollers being annaann, as.
